Radiations, Alpha, Beta, Gamma - Advantages and Disadvantages

The Ancient civilizations were a safe place to live in. There were no industries during that period. People lived in natural environments and had fresh air to breathe in and breathe out. The food that they ate was by hunting and from the farms that they cultivated in their land. They kept their land very fertile and trees around them. They had plenty of food and water to eat and drink. They lived in very peaceful environment. As development took place, they cut down all the trees around them. Then people discovered more to make a better place to stay and found comfort in their living. Through agriculture and industrial revolutions the small scale and large scale industries came up. Man invented a lot of things and developed infrastructure and facilities.

Man turned more scientific and discovered the nuclear activity and radiations as the world wars approached. He used a lot of these during the World Wars. Today, all those inventions have turned negatives in numerous ways and are affecting the human life and health. When I sit in front of my television or internet powered by Dish TV Offers. I get to watch a lot of this new featuring on this topic. The Radiation impact has become so very serious, that today we find a lot of Scientists researching on this topic to protect life on earth. They say if this state continues then it could turn out to be devastating.

So having spoken so much, let us look at what we understand by the term 'Radiation'. Radiation helps in transmitting energy in many forms. This could be in form of light or in tiny particles which are very small in size and is some very difficult to view even through the naked eye. The visible light is the Ultra violet light that we received from the sun and sun beds. It can also in the form of transmission for the television and Radio communications that we find in our day to day life. If we dig deep into the subject, we will find more number of terms and definitions and the subject is so vast that leads to more inventions. However, most of us know that there are three principles of the radiations. They are the Alpha, Beta and Gamma rays or particles. This we might remember studying during our school days as well.

So let me recollect some of them in one or two points that we eventually studied in school. The Alpha particles consists of two proton and two neutrons and are considered as naturally-occurring heavy elements such as Uranium and Radium. These can also be man-made transuranic elements. These radiations are so powerful that they can easily penetrate through the skin and are considered dangerous if emitted inside the human body. The Beta particles are fast moving electrons and are more penetrating than the alpha particles. These particles can be stopped from penetration by use of wood or aluminum. They have the capacity of passing through the human flesh however, less harmful compared to the gamma. The Beta radio-active particles can be stored in sealed containers. The third type is the Gamma radiations which are high energy beams which are similar to the X-rays. These are emitted in many radioactive decays and are so penetrating, when sealed requires substantial amount of shielding. These are used in industrial gauges and radiotherapy machines. The other kinds of radiations are cosmic radiations and Neutrons.

Today, radiation can be described as a double edge-sword. Radiations are useful in many aspects. Radiation itself is a useful tool for research; medical diagnosis and therapy; materials processing; non-destructive testing; sterilization of instruments, pharmaceuticals, food, and mail; and inhibition of sprouting. However, Radiations are harmful in many aspects and as discussed earlier can be very harmful. It increases the frequency and severity in health hazards and can be extremely dangerous.

Stuart is a freelance writer who generally writes topics on culture and farming. He finds a lot of time to watch TV powered by Dish TV Offers. Sometimes he lies on his couch and starts thinking about weird things in life. The rest of the time writes articles on topics that interest him. Today he wants to share his thoughts on Radiation and its effects.

This page describes about gamma knife surgery, cost, low cost and advantages in India; along with the conditions, procedures, preparations, follow up and risks – Dr.Dheeraj Bojwani Consultancy a leading medical tourism provider in India.

The gamma camera allows a further examination of the human body that extends beyond anatomy and structure alone. With this machine there is a non-invasive way to monitor internal organs, discover possible problems in the early stages, and verify if a patient is responding to the treatment.

There are many things that cannot be seen with the unaided eye. If a person wants to see radioactive isotopes, they will need a gamma camera. Being able to see surroundings in a different way can help protect people from what is around them.

It is important to know what are these solar energy advantages and disadvantages. Undoubtedly, you have read or heard about alternative power generator or renewable energy supply. In one way or the other, you have encountered these terms. At any rate, the most significant aspect of the energy/power terminology is getting rid of the pricey utility bill – for good!

The focus of this article is to look at the led light bar, and its advantages and disadvantages. This article will help understand why led bars are so popular as well as discover the draw back of a led light bar. This understanding will help one to choose for themselves if they would like to use the led light bar or continue using the more traditional light bars such as strobe and halogen.

One good way to stay away from the negative effects of the cell phone is by using the headset while talking. The main thing is to keep the cell phone at a moderate distance while talking so that it doesn’t harm the brain cells.

To meet the requirements of environment protection, there are more and more new energy for using in daily life or industry. Compared with the fossil fuels like coal, petroleum, natural gas and so on, solar energy has the following obvious advantages:
